Device not detected?
If your browser or wallet cannot see the Trezor device, try the following checks in order:
- Confirm the USB cable and port work with other devices.
- Reconnect the device and ensure it is unlocked and on the device home screen.
- Restart the Bridge service (or reinstall Bridge) and refresh the web page.
- Try a different browser that is known to support the Bridge interface.
Driver and permission issues
On some systems, USB drivers or permissions can prevent Bridge from accessing the device. Ensure your OS has correct USB drivers installed and that you have granted permission for the browser to access connected devices. On certain operating systems, administrative privileges are required to install Bridge or its drivers.
Interference from other software
Software that manages USB devices, virtualization platforms, or security tools can interfere with Bridge. Temporarily disable or configure such software during troubleshooting. Avoid running other wallet managers or multiple Bridge-like services simultaneously to prevent conflicts.
Stability and intermittent failures
If connectivity is intermittent, test the device on another machine to isolate hardware issues. Faulty USB cables and ports are common causes. If the device operates reliably elsewhere, replace or repair the problematic computer or cable.
When to update or reinstall
Corrupted installations can cause persistent errors. Reinstalling Trezor Bridge using the official installer often resolves these issues. Before reinstalling, back up any local settings you require and follow official guidance for a clean reinstall. If troubles continue, contact verified device support with logged error messages for assistance.
Applying these methodical checks usually resolves the majority of Bridge connection problems and gets you back to safely signing transactions on your hardware wallet.
